Rancher_State Partition size

I am using RancherOS and Rancher 2.0 on baremetal and looking for recommended partition sizing for the Rancher_State. I followed an old doc https://www.cnrancher.com/docs/os/v1.x/en/about/custom-partition-layout/ I found and 3Gb seams to be too small as I am getting Kubelet has disk pressure on that node now.

What all lives in that Rancher_State is it just the OS and Rancher 2.0 or will other containers that are added also take up space in that partition?

Maybe you can use df -hT to check that disk and directory. The disk with the label of RANCHER_STATE will contain the RancherOS ROOTFS.
